🔥 Significant Power Gains
When paired with professional tuning, this setup may deliver an increase of approximately 30–80 horsepower, helping improve acceleration, towing response, and overall driving performance.

Improved Fuel Economy
Real-world results may show a 2–5 MPG improvement by reducing exhaust restriction and eliminating the extra fuel consumed during DPF regeneration cycles.

Faster Turbo Response
Lower exhaust backpressure allows the turbocharger to spool more quickly, providing sharper throttle response, smoother acceleration, and stronger performance under load.

🛡️ Lower Maintenance Costs
Eliminating the factory aftertreatment system may reduce ongoing expenses related to DPF cleaning, DPF sensor replacement, and DEF refilling.

🌡️ Lower Exhaust Gas Temperatures
The free-flowing 4-inch exhaust design helps move hot exhaust gases more efficiently, reducing sustained exhaust temperatures during towing, heavy loads, and demanding driving conditions.

🔧 Supports Longer Engine Life
Reducing the heat stress associated with repeated DPF regeneration and minimizing EGR-related carbon buildup may help lower the risk of certain long-term engine and emissions-system problems.

4-Inch Downpipe-Back Exhaust System for 6.7L Powerstroke

Designed for 2011-2019 Ford F-250 and F-350 trucks, this kit replaces the factory exhaust components behind the turbo downpipe, including the DPF, SCR catalytic converter, and exhaust piping assembly.

Unlike a short DPF replacement pipe, it provides a full Downpipe-Back route from the turbo outlet to the rear of the truck for more complete airflow optimization.

Please note: This system connects behind the existing downpipe and does not replace the turbo downpipe.
Turbocharger → Downpipe → Downpipe-Back Exhaust → Rear Outlet

How Much Can a DPF Delete Save?

The factory DPF system can create ongoing costs through regeneration, cleaning, sensor repairs, and complete DPF replacement.

  • DPF cleaning service costs
  • Extra fuel used during active regeneration
  • DPF assembly replacement
  • Emissions-sensor repair costs
Savings ItemEstimated Amount
Fuel Cost Savings$21,000
DPF Maintenance/Replacement$6,200
Gross Savings$27,200
Kit + Tuner Cost-$1,200
Estimated Net Savings≈ $26,000
Based on typical use over 300,000 miles. Actual savings vary by fuel prices and driving conditions.

Optimized 4-Inch Exhaust Flow

The full-length 4-inch mandrel-bent tubing maintains a consistent diameter without wrinkles or bottlenecks.

  • Smooth bends: Support unrestricted exhaust flow.
  • 4-inch diameter: Increases flow and reduces backpressure.
  • Precision TIG welding: Helps prevent leaks and improve durability.

The improved flow supports engine efficiency under towing or heavy-load conditions. The 4-inch design also delivers a deeper exhaust note without the more aggressive sound commonly associated with a 5-inch system.

Power and Driving Response

With proper tuning, improved exhaust flow may provide:

  • Faster turbo response
  • More responsive throttle
  • Lower sustained exhaust gas temperatures
  • Smoother acceleration under load

Depending on the setup, gains of 30-80 horsepower or more may be possible, along with a deeper and stronger exhaust sound.

Installation and Tuning

  • Tuning is required to prevent warning lights and diagnostic trouble codes.
  • A tuner is not included.
  • Designed for off-road and competition use.
